Background Art

[0002] In recent years, with the continuous innovation of beauty instrument product functions, the functions of beauty instruments have evolved from simple basic skin care functions such as heated steam and facial cleansing to more technologically advanced beauty instrument products such as microcurrent, ultrasound, radio frequency waves, and LED. At the same time, the cleaning parts of beauty instruments have also evolved from cheeks to subdivided areas such as the eye area, forehead, and neck. The product functions include lifting and firming, cleansing and hydrating, acne removal, and freckle removal. This has greatly expanded the market richness and product variety of the beauty instrument industry, which is conducive to stimulating the in-depth development of the subdivided fields of the beauty instrument industry, thereby driving the continuous expansion of the market size of the beauty instrument industry.

[0003] Traditional beauty devices, especially those using electrical stimulation technology, often cause users to feel tingling due to sudden changes in current levels during the current output process. This discomfort reduces the user experience and may affect the beauty effect. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a beauty instrument control method for optimizing body sensation, which is suitable for electrical stimulation beauty instruments. It can reduce the tingling sensation, reduce the muscle fatigue caused by electrical stimulation, and give the muscles a process of adapting to the electrical stimulation, thereby improving the user's comfort and satisfaction.

[0005] In order to achieve the above object, the present invention provides a beauty instrument control method for optimizing body sensation, and the specific steps include: The control signal is obtained and the PID algorithm is used to adjust the control signal so as to control the first pulse of the output pulse group to be opposite to the pulse of the previous pulse group.

[0006] Preferably, the output voltage is input into the electrode group, the effective values ​​of the voltage and current in the electrode group are detected, and the impedance at different frequencies is calculated; and the resistance and capacitance values ​​used for identification are calculated based on the impedance value.

[0007] Preferably, if it is detected that the resistance becomes smaller, the output pulse width and the voltage limit become higher; if the capacitance becomes smaller, it means that the contact area becomes smaller, and the output pulse width and the voltage limit become lower.

DETAILED DESCRIPTION

[0012] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0013] Among them, the EMS AC level is mainly used to control the positive and negative of the first pulse of the pulse group. Studies have found that when the first pulse of the current pulse of the pulse group and the first pulse of the next pulse group are at the same level, the body is prone to feel uncomfortable. Otherwise, the comfort will be better. Therefore, the controller controls the first pulse of the output pulse group and the pulse of the previous pulse group to be opposite, thereby improving the body sensation.

[0014] like Figure 1 As shown, the present invention provides a beauty instrument control method for optimizing body sensation, and the specific steps are as follows: The control signal is obtained and the PID algorithm is used to adjust the control signal so as to control the first pulse of the output pulse group to be opposite to the pulse of the previous pulse group.

[0015] Specifically, the present invention increases the buffer level during the current output process to optimize the current waveform, thereby reducing the tingling sensation caused by the sudden change in level. By changing the pulse timing control, the muscle fatigue caused by electrical stimulation is reduced, and the output voltage is changed from weak to strong, giving the muscle a process of electrical stimulation adaptation, thereby improving the user's comfort and satisfaction.

[0016] In the present invention, the buffer level is regulated by a specifically added level buffer circuit, which adjusts the switching frequency and output voltage of the voltage buffer device through the PID algorithm, so that the voltage increases from weak to strong and the output pulse width increases from narrow to wide, ensuring the stability of the current output, thereby providing a process for muscle adaptation.

[0017] The method is applied to a beauty instrument control system, which includes: a controller, an EMS power module, an EMS output module, an electrode array and a current detection module connected to each other. When adjusting the output module, a level buffer circuit is set in the EMS output module. The controller controls the output voltage to gradually increase by adjusting the buffer circuit.

[0018] Regarding moisture and contact control: The present invention obtains the effective value of voltage and current on the electrode, calculates the impedance, detects the impedance at two different frequencies, and finds the resistance and capacitance values. When the resistance is detected to be smaller, the output pulse width and voltage limit become higher; when the capacitance is smaller, which means the contact area is smaller, the output pulse width and voltage limit become lower, reducing the possibility of tip discharge. Among them, the output voltage waveform before and after optimization is compared, such as Figure 2 shown.

[0019] For the setting of pulse width and voltage limit, the steps are as follows: select several membrane cloths of different areas, set the pulse width between 10us-100us, and the voltage limit between 5V~40V. According to the scores of different users on the electric stimulation test, the maximum pulse width and voltage corresponding to the electric stimulation that the user can accept are set as the limit. The membrane cloths of other areas use this limit as a linear relationship.

[0020] Among them, the process of PID algorithm adjusting the output voltage is: Identify the current voltage, compare it with the set voltage, calculate the current voltage deviation to get the proportional value, calculate the integral value by calculating the sum of the deviations over a period of time, and get the differential value by calculating the difference between the deviations. The voltage calculation value is obtained by combining the three regulation rules of proportional, integral, and differential. Among them, proportional regulation is used to calculate the current error, integral regulation is used to continuously accumulate the deviation, and the error is zero during steady-state regulation, which plays a role in eliminating ripples. Differential regulation can predict future errors and play a role in rapid regulation.

[0021] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
